CPU notifier is present for creating device entries for child node "cache" under parent node "cpu" as per DT. During resume from suspend, while booting all non-boot CPU's, this notifier for adding cache device gets called before cpu device is added by device_resume. Because of this warning message of "parent should not be sleeping" comes during resume. Removing the notifier to explicitly add/remove cache device as CPU and cache device get added/removed anyway as part of normal suspend resume sequence. dpm_resume_end - > dpm_resume -> device_resume Signed-off-by: Sumit Gupta <sumitg@xxxxxxxxxx> --- drivers/base/cacheinfo.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/drivers/base/cacheinfo.c b/drivers/base/cacheinfo.c index e9fd32e91668..17d9c051a16f 100644 --- a/drivers/base/cacheinfo.c +++ b/drivers/base/cacheinfo.c @@ -544,8 +544,6 @@ static int __init cacheinfo_sysfs_init(void) goto out; } } - __hotcpu_notifier(cacheinfo_cpu_callback, 0); - out: cpu_notifier_register_done(); return rc; -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
